Songs Music Publishing president Ron Perry told Billboard: “She’s going to be a really big songwriter outside of Lorde. She’s going to have a lot of big songs out there as Ella (Yellich O’Connor), she’s a once-in-a-generation type artist.”

Lorde’s single ‘Royals’ topped the US charts for a sixth week this week. She is the youngest female chart-topper in 25 years and also the first person from New Zealand to score a US number one. Her album ‘Pure Heroine’ has spent five weeks in the US top ten, and the song remains in the UK top five after three weeks. Earlier this week, she performed at Tilda Swinton’s birthday party, with guests including Karl Lagerfeld, David Bowie, Anna Wintour, Princess Eugenie and Sofia Coppola.

Lorde also recently unveiled a preview of her cover for Tears For Fears’ ‘Everybody Wants To Rule The World’, which will feature on the forthcoming The Hunger Games: Catching Fire soundtrack.
